Anas bin Malik reported,

They asked, "Messenger of Allah, is the pilgrimage to be performed every year?"He replied, "Had I said yes, it would have become obligatory, and had it become obligatory, you would not have been able to fulfill it, and had you failed to fulfill it, you would have been punished."
